Very convenient.
"I believe it to be as efficient as paste-type, if not more so. If needed, I can cut it down to "chips". Granted the seams need to be fairly tight/close together and best to use a torch that is micro or small so as not to melt more than needed. Great for repair works and attaching small parts. The only downside I find is that you only get so much wire compared to other solder types of this metal and it essentially costs more. But for efficiency, it's worth it."
